About Me

I am a Beatriu de Pinós fellow at the University of Barcelona since March 2025.

I finished my PhD in 2018 at the University of Illinois at Chicago under the supervision of Brooke Shipley.  After that, I worked as a postdoctoral researcher with Boris Chorny at the University of Haifa for 2 years. I was a postdoc at the Sorbonne Paris Nord University with Christian Ausoni between September 2020 and August 2021, at the City, University of London between September 2021 and August 2024 under Joseph Chuang and at LMU Munich with Markus Land between September 2024 and March 2025.

Research interests: Homotopy Theory, Algebraic K-theory and  Homological Algebra
